What is used to disinfect a swimming pool?
Disinfecting a swimming pool is crucial; improper handling can turn it into a breeding ground for diseases. The suitable temperature of swimming pool water provides an ideal environment for pathogens such as typhoid, paratyphoid, dysentery, hepatitis, acute conjunctivitis, and pyogenic diseases. Hepatitis and encephalitis viruses are often waterborne, making disinfection essential. Today, let's explore the methods used for swimming pool disinfection.
The most common method for swimming pool disinfection is chlorination. Chlorine in water produces hypochlorous acid, which diffuses to the bacterial surface, penetrates the cell membrane, and enters the cell. The oxidation of chlorine atoms disrupts the enzymatic systems within the bacteria, ultimately leading to their death.
A key feature of chlorine disinfection is the ability to maintain an appropriate level of residual chlorine in the pool water as needed. This ensures continuous disinfection of pool water constantly exposed to human contamination. Generally, the required residual chlorine level in swimming pool water is 0.4–0.6 mg/L. Furthermore, to ensure disinfectant efficiency and prevent corrosion of pool equipment and surfaces, the pH of the swimming pool water should be maintained at 7.4–7.6.
